🌸 About Hanami

See the Alpha before it blossoms.

The Story

In Japan, Hanami (花見) is the centuries-old tradition of gathering under cherry trees to witness their blossoms at peak bloom. The window is achingly brief — often just a week. Those who arrive early see the most beautiful moment. Those who arrive late find only fallen petals.

On-chain Alpha is no different. Smart money moves first, and the window between "undiscovered" and "everyone knows" can be measured in minutes. By the time a token is trending on social media, the smartest wallets have already positioned themselves — and the bloom is fading.

Hanami brings the spirit of cherry blossom viewing to Robinhood Chain. We watch the smartest wallets in real-time, detect their moves as they happen, and help you position yourself alongside them — before the petals fall.

Our Mission

To democratize on-chain intelligence. Every wallet address, every transaction, every token contract on Robinhood Chain is public data — but raw data isn't insight. Hanami turns public blockchain data into structured, actionable Alpha signals that anyone can use, for free.

What We Built

Hanami is a smart money tracking and Alpha signal analytics platform built exclusively for Robinhood Chain (Chain ID 4663). Here's what makes it different:

100% on-chain data — No off-chain signals, no social sentiment, no paid promotions. Every signal traces back to a verifiable on-chain transaction.
Behavioral smartness scoring — We don't just track "whales." We score every wallet on token diversity, trade frequency, timing, and P&L to find genuinely smart traders.
Three signal engines — Smart Buy (consensus), Whale Movement (large transactions), and Alpha Consensus (multi-signal overlay) work together to filter noise from signal.
Completely free — Dashboard, API, real-time SSE push. No paywalls, no tiers, no "premium" features.

Technology

Hanami is built on a transparent, fully on-chain data stack:

📊 Data Pipeline

Layer	Technology
On-chain data	Blockscout RPC — full-node access to Robinhood Chain transactions, contract calls, and event logs
Token data	DexScreener API — real-time token prices, liquidity, volume, and pair metadata
Signal engine	Custom behavioral analysis engine — smartness scoring, signal generation, and consensus detection
Real-time push	Server-Sent Events (SSE) — 15-second interval push for overview, wallet activity, and signals
API	RESTful JSON API — free public endpoints for wallets, tokens, signals, and activity feeds
Frontend	Vanilla JS SPA dashboard + static content pages (no framework bloat)

Blockchain: Robinhood Chain

Robinhood Chain (RH Chain) is an Arbitrum Nitro Layer 2 blockchain with Chain ID 4663. It features low gas fees, full EVM compatibility, and support for smart contracts and DeFi applications. Hanami is built specifically for the Robinhood Chain ecosystem — we don't track other chains, because focus is what lets us go deep.

Commitment

Transparency — All data sources are public. Every signal can be independently verified on Blockscout and DexScreener.
No investment advice — Hanami provides data and signals, not financial advice. Always do your own research.
Free forever — The dashboard, API, and all data features will remain free. This is a tool for the community.
Privacy-first — We don't collect wallet addresses, don't require login for basic features, and don't track your browsing. See our Privacy Policy.
